Abstract: Selenium is an essential trace element of human-being.Selenium deficiency can lead to a series of human disease.Therefore, researches of Se-rich edible oil cause extensively attention in China. In order to sort out the research and development status of Se-rich oil product, and to predict the development of Se-rich oil in the future, this paper summarized the selenium-enriched method, the research status and the existing problems in Se-rich oil manufacturing. At the same time, the domestic and overseas selenium-enriched standard was introduced. Finally, the development trend of selenium-enriched edible oil in the future was predicted: adapting selenium-rich garlic essential oil as natural antioxidant additive maybe a very interesting way, some of the selenium-rich algae hydrolysates may be a satisfactory gellant alternative for selenium-rich gel oil production.
